TubeGist — YouTube Summary Sidebar

Summarize any YouTube video in seconds — without giving up your privacy. TubeGist adds a side panel to YouTube that pulls the video transcript and turns it into a clean summary with clickable timestamps, so you can jump straight to the parts that matter. Unlike other summarizers, TubeGist is built privacy-first: • No account, no login. Nothing to sign up for. • No server, no tracking. Your transcripts and summaries never touch our servers — there are no servers. • Bring your own API key. TubeGist calls the Anthropic Claude API using your key, stored only on your device. You pay Anthropic directly for exactly what you use (cents per summary with the low-cost Haiku model). WHAT YOU GET • One-click summaries: TL;DR, key points, and notable moments • Clickable timestamps that seek the video • Full transcript view, every line jumps to that moment • Choose your summary language (English, 繁體中文, Español, 日本語, and more) • Works on regular videos and Shorts FREE VS PRO Use it free up to 3 summaries per day. A single one-time purchase unlocks unlimited summaries — no subscription, no recurring fees. HOW IT WORKS 1. Install TubeGist. 2. Open Settings and paste your Anthropic API key (get one at console.anthropic.com). 3. Open any YouTube video, click the TubeGist icon, and hit Summarize. TubeGist is open about what it does: it reads the transcript YouTube already provides and sends it to Claude with your key. That's it.
